is it just me, or does Diana's early game...suck? (Mid and Top)

I'd like to say that i'm just an average player, I'm not really amazing but I'm not absolutely horribad either, I also do fine with Diana, I know how to dodge skill shots and ik how to build when going against certain champs early game... Mid But, pre 6, I sometimes get that one player that KNOWS I can't get cs and trade back all at once, its either I save my Q to trade damage when I get poked in mid lane, or save it to get some cs, otherwise, I get constantly auto attacked by mages and risk getting low enough for them to all in me. Top I normally get W first top lane, however, I find myself getting outpoked there as well, the usual tops simply out damage me when it comes to melee range (Obviously because they build AD, but I notice that not even my W and passive are helping me keep up).

Of course, once I hit 6, I'm absolutely fine, but if my opponent knows how to bully me out of lane, I'm afraid by that time I'm left behind, would it be too much to ask for a simple early game buff that won't affect her mid-late game? or am I just being stupid?
